Error description
APAR IC62304 describes a problem where backups to a disk storage pool with caching enabled can fail if the storage pool is full of cached data. Even if the fix for APAR IC62304 has been applied, there is a small window where backups of (very) large files to such a disk storage pool can still fail with the same symptoms. . . Customer/L2 Diagnostics: The Tivoli Storage Manager client shows for example (dsmsched.log): [...] 10/28/2009 09:53:19 ANS1228E Sending of object '\\test-machine\c$\large_dir\file1.trn' failed 10/28/2009 09:53:19 ANS8010E An attempt to backup or archive a file has exceed the maximum number of retries. 10/28/2009 09:53:19 ANS1228E Sending of object '\\test-machine\c$\large_dir\file2.trn' failed 10/28/2009 09:53:19 ANS8010E An attempt to backup or archive a file has exceed the maximum number of retries. 10/28/2009 09:54:30 ANS1802E Incremental backup of '\\test-machine\c$' finished with 2 failure . Usually there is no message seen in the ACTLOG at this time, but the above message may be accompanied by "ANS1329S - server out of storage space" (but not necessarily). .

Tivoli Storage Manager Versions Affected: Tivoli Storage Manager servers 6.1 on all platforms . . Initial Impact: Medium . . Additional Keywords: zz61 IC62304 cache caching migrated migration
Local fix
Empty the affected storage pool manually using the following command against all volumes in the pool: MOVE DATA <volume_name> and set "Cache migrated data" to NO to avoid the storage pool to fill up and backups to fail again.
